First, Please no rude answers or comments - you don't need to show everyone that you don't have a life :)

Ok... I have to make a physics scrapbook that has 4 pictures in it. So, i have to take 4 pictures that have to do with physics and under each picture I have to write 1 paragraph explaining how the picture deals with/ relates to physics.

Any ideas of what I should take pictures of?
1. I thought maybe a car driving (motion)
2. Also, a bouncy ball or throughing a pencil in the air (gravity)
3.4 and more ideas ..... best answer 12 points :)

Assume that all sides are 1 cm long. Pattern is here: http://img227.imageshack.us/img227/1777/patternux8.png I got 398 cm but my teacher told me that wasn't it. Teach me, please. Thank you. All I need is the number of squares. I don't know the pattern. I'm fine with the perimeter.

1.it says compare the four main layers of the atmosphere which are:the troposphere,stratosphere,mesosphere,thermosphere..

2.identify the two atmospheric layers that contain air as warm as 25 degress C.

3.calculate how much colder air is at the top of mount everest, dewhich is almost 9km above sea level ,than air is at the indian coastline(hint:on average the temperature in the troposphere decreases by 6.5 degress C per kilometer of altitude.

4.which industrial city would have fewer air pollution incidents related to temperatureinversions:one on the great Plains or one near the rocky mountains?explain

5.in 1982 larry walters rose to an altitude of approximately 4,900m on a lawn chair attached to 45 helium filled weather ballons.Give 2 reasons why walters trip was dangerous.

Thought experiment :
A
Imagine a vast machine, bigger then the accelerator at C.E.R.N,
massive, or in fact you could imagine it desk ornament size come to think of it

And what it does is this...

There is say a 1000 meter perfectly engineered shaft, down which a say a massive ball is dropped, also perfectly engineered, the ball accelerates down the shaft, the shaft after the drop curves around using the momentum from the drop of the ball, the ball then goes up the extremely well engineered and tested ramp, back up to another shaft parallel shaft which has all of the many many balls on a water mill type of bucket system, so that when a ball drops into its waiting basket, or bucket, at the bottom of the said second shaft... this weight on the "ball mill" then causes the mill (also very exactly engineered) to drop down one space with weight of said ball, this in turn causes top ball to tilt over the edge and start its plummet down the 1000m shaft , and around back to the "mill"

it seems like spiders and other bugs are always in the shower, or other areas of the bathroom. They could come from an open window, but I always find more in that room than other rooms with windows.
